International Trade Administration Commission (ITAC) of South Africa, Report no. 380 of 2 September 2011, "Reduction in the customs duties on lysines and its esters; and feed supplement containing by mass 40 per cent or more lysine, whethe or not containing added antibiotics or added melengestrol acetate": http://www.itac.org.za/upload/document_files/20140928110511_Report-380.pdf

On 14 October 2011, upon the advice of the International Trade Administration Commission of South Africa (ITAC), the South African Revenue Service (SARS) eliminated the import tariffs on lysine and its esters (HS 2922.41), and feed supplements containing at least 40% (by mass) of lysine (HS 2309.90.65).

Previously, the tariff stood at 10% ad valorem. EU and EFTA member states are not affected by the measure, since those countries already enjoyed duty-free access to South Africa.
